lhis invention relates to disassembling apparatus and more particularly to an apparatus .for

simultaneously removing a plurality of spacing sleeves from-an article.

In the assemblingof certain: electronic units, spacing sleeves are-used "to-accurately space a plurality of pins in apertures in a shell memher while the pins :are brazed to a supporting member. Upon completion of thebrazing of the pins to the supporting member, the spacing sleeves, which are rather tightly gripped by the contacting parts, must be removed.

It is an object of the present invention to provide a simple-:andeflective device for rapidly disassembling parts.

In one embodiment of the invention, there is provided a mom: er for supportin the article in a predetermined position with the parallel notched spacing sleeves projecting therefrom in alignment with a 'i'eciprocable head comprising a circular extractor member-having -.a series of spaced teeth thereon movable between the sleeves to a position in lateral alignment with the notches therein and being rotatableato move the teeth. into the anotches of the sleeves; the extractor member having an operating lever engaging therewith for retracting the head and removing the notched sleeves irom'thearticle. A member reciprocable with the extractor member and having as'eries-of pins for engagin the end portions of the sleeves isprovided in the head for supporting the sleeves moved and. an ejector member normally movable with the head and -'cap-abls.ol movement rclative thereto is provided and "engages'the of the sleeves 'ior ejecting them from the supporting members after the .sleeveshave been re moved from the article and the retracting member'zhas been rotatedtto-its normal-starting po- Simon...

Extending horizontally from the Wall 28 is a member 35 (Fig. 2) for supportin the article l in a predetermined vertical position.

A head 31 is mounted for horizontal movement into engagement with the end portions of the spacing sleeves I8 and comprises an annular extractor member 38 (Figs. 4 and 7) secured, as by rivets 39, to a circular flange 40 of a hollow shaft 4|. The shaft 4| is axially and rotatably mounted in a bearing aperture 42 of a 'supporting member 43 secured to the base plate 26. The annular member 38 has an inner cylindrical surface 45 and is provided at its forward end with an inwardly directed flange 46, which is formed with a plurality of evenly spaced circular notches 41 formin a series of inwardly projecting catchelements or teeth 48 therebetween.- The teeth or; shoulder elements 48- of the extractor member are arranged to fit between the spacing sleeves I8 when the extractor head 38 is moved to its forward position, as indicated in dot and dash lines in Fig. 4, where they are stopped in lateral alignment with the notches 20 in the sleeves l8. Upon a limited rotary movement being imparted'to the extractor member 38, the teeth 48 thereonwill' engage in the notches 28 ofthe spacing sleeves l8 and, upon an axial movement to the right being imparted to themember 38, the teeth 48 thereof will engage the shoulder-s 2| of the spacing sleeves l8 and remove-the sleeves from the ar- On the right hand end of the shaft 4|, a collar member 49, havin v a hand wheel or flange 50, is secured by means of pins The hand wheel 50 is provided 'with'a notch-52, the shoulders 53 and 54 of which-alternately engage a stationary horizontally disposed rod 55 secured to the support 43to limit the angular or rotary movement of the extractor member 38 when the member 56 is turned in opposite directions. Engageable with the left hand end of the collar 49 are the furcated ends 51 of a bifurcated operating lever 58 fulcrumed at 59 in a supportfifl mounted on the base 26. The-furcated ends 51 straddle the hollow shaft 4| "and, upon actuation of the operating lever 58, engage the member 49- to move the shaft 4| and the head 31 to the right during a sleeve extracting movement. When in the position shown in'Fig. '1, Where they engage the support 43, the fur-cations 51' act as-a stop to engage the collar 49 and'limit the movement of the head 31'to the left to StO'p'the teeth 48 in lateral alignilnent with the notches 28 of the sleeve member 'Thehead'31 maybe rotated by manually en'- gaging the head 31 or the handwheel 5|] andapplying aturn'ing force'there'to, it angular movement being limited'by 'the engagement of the opposite shoulders'53 and the rod 55. The head 31 may be advanced into engagementwith the'sleeves l8 by manually engaging the head 31 or the hand wheel 58 and applying a "force thereto and the extracting movement of the'head 31 to'theright is imparted thereto by the actuation of the operating lever 58 in a clockwise direction, as viewed in Fig. 1. A

spring'62'is provided to return the operating lever 58 to the position shown inFig. 1.

In'order toyprevent the ends of the spacing sleeves |8 from 'be'c'omingdistorted and deformed 54 on the hand wheel 38with during the extracting operation, means are provided in the head 31 to support the ends thereof and comprise a series of pins 64 mounted on a disc 85 of a sleeve supporting member 66. The pins 64, arranged in a circle and in coaxial alignment with the sleeves l8, are adapted to fit into and support the end portions of the sleeves when the head 31 is moved to'its forward o rfleft hand position. The sleeve supportingmember 66 is mounted for axial movement with the extractor member 38 and has a shank 61 mounted within the hollow shaft 4|. An arm 68, secured to the end of the shank 61 to maintain the supporting I member 66 in assembled relation with the shaft 4|, is slotted at 66 to receive the rod 55 therein to prevent angular or rotary movement of the sleeve supporting member 66. The forward portions of the pins 64 are cut away at 16 to provide clearance for the teeth 48 when the pins 64 are in engagement with the sleeves l8 and the retractor member 38 has been rotated to bring the teeth 48 into engagement with the slots 20 of'the sleeves l8.

After the sleeves |8 have been removed from the article |8, they remain in the head 31, being retained on the pins 64 by the teeth 48 of the extractor member 38. An ejecting member 15 is provided to eject the sleeves I8 from the head 31 after the extractor member 38 has been rotated to remove the teeth 48 from the slots 20 of the sleeves IS. The ejector 15 comprises a disc 16, which isengageable with the ends of the sleeves I8 and is notched at 18'|8 to slidingly engage the pins 64. The disc 16 is formed on one end of a rod 19 mounted in a bore 88 of the shank 61 of the sleeve supporting member 66. The rod 13 projects beyond the shank 61 and has a collar 8| secured to its end in spaced relation to the end of the shank 61 and the ejector member 15 is urgedto the right and maintained in its normal position relative to the member 66 by a coil spring 82 interposed between the collar 8| and of the shank 61 (Fig. 1). By relative movement between the ejector member and the sleeve supporting'member, the sleeves may be ejected from the head 31. I

A stop member 85, mounted in a post 86 on the base 26, is positioned in the path of movement of the rod 19 to stop it, after a predetermined move- 50' ment thereof, in a |8 will have been position in which the sleeves removed from the article ID. By a further turning movement of the lever 58, the extractor member 38 and the sleeve supporting member 66 are moved relative to the ejector 15 to withdraw the pins 64 from the ends of the sleeves l8, whichthen'fall through an aperture 90 in the base 26 into a receptacle 9| provided to receive them. I i 1 In the operation of the disassembling appara tus, the article It! is seated in the supporting member'21, with the sleeves 8 projecting. to the right, as viewed in Figs. 1 and 2. With. the extractor rotated to the position shown in Fig. 7, the head 31 is moved to the leftuntil stopped by the furcations 51 to advance the teeth 48 on the extractor member between the sleeves l8 to a position in lateral alignment with the notches 20 therein, after which the member 38 is rotated to move the teeth 48 intothe notches 280i the sleeves l8. With the head 31 in its forward position, the end portion of the sleeves l8 will snugly engage and be supported by the supporting pins 64 of the supporting member 66 and the end surface of the sleeves will abut against the ejecting member- 15. 'I-heactuatin'g lever 58 may then be actuated in aclookwise direction to move the head 31 to the right, as viewed in 'Fig, "1, to; remove the pins l8 irom the article in. When the rod .19 engages the stop 15,111 which position of the head 31 the sleeves [tare free of the pins. l5, the rotation of the lever 58- may be halted momentarily and the extractor member 38' rotated'to disengage the :teeth 48 from theznotches 20 of the sleeves, after which the lever 58 maybe moved further in a clockwise idirection'to cause continued movement 'to the right of the extractor member 38 and the sleeve supporting member '68 to eflect the ejection of the sleeves 18' from the headi3'l, as shown in Fig. '6, andper-mit the-sleeves to drop into the receptacle 921.
